Some companies in order to better show in the body image and enhance the visibility, most of the use of high cost of neon lights as a means of publicity. The various uses of neon lights are gradually being developed and applied, and this is related to how fast and convenient control of these neon lights out, flicker, has become an inevitable problem. The system based on PLC controller, through the program to achieve the happy holidays four word around six neon also shining 1s and in accordance with the order followed by bright 1s, when all words are lit up after, again at the same time bright 1s, then in reverse order in turn the bright 1s, the time interval is 1s. And the top of each word and the bottom of the five neon lights are in accordance with the order of a certain book light. If you need to change the effect of neon lights, only need to change the program can be simple and easy to operate, so the PLC based control system for the use of neon lights. Through this research, we can intuitively feel the control ability of PLC for the neon lamp particularly strong, at the same time, PLC fast, simple, effective, convenient and more worthy of our further understanding of the, in the applications of master PLC, at the same time, but also to further the development of PLC in other areas.
